Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson plan starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

As part of a career exploration and investigation, learners research the Internet for possible career options and identify what type of educational preparation is required for those careers, as well as possible salary options,...

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

Class members engage in a STEM experiment and investigate how materials affect heating in a house by creating models of houses and using different top surface materials. They record the temperature inside the models and consider what the...

Sample pennies to gain an understanding of their ages. The 16th installment of a 25-part series requires groups to collect samples from a jar of pennies. Pupils compare the distribution of their samples with the distribution of the...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

Young scholars investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information...

Learners participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Emerging electricians extend mental models of light bulbs and resistors in series and or in parallel circuits to include the connection of photovoltaic cells in arrays. They investigate open circuits, using a DC voltmeter, a light...

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this activity is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions....

Dig in! Middle schoolers learn about archaeology by exploring the remnants of the Chiribaya bodies found in Illinois. Compare archaeological investigations, and then write a mystery detailing the discovery of a body! Consider bringing in...

Students investigate mechanical weathering as a form of erosion. In this erosion lesson, students, define weathering and erosion before determining how the Earth's surface is in a constant state of change. They watch a video, access...

Young scholars design their own playground equipment. In this design instructional activity, students take pictures of equipment they like and make a class pictograph of their favorite ones. They investigate the design, research...

This lesson is intended as preparation for a school health fair but could be used anytime. Learners discuss and compare the nutrition found in typical snack foods. They compose investigative questions, collect data, and research a...

After investigating different policies within the school district, young reformers select a policy they would like to change. They then investigate the policy, and craft a letter in which they advocate a change to the policy. For guided...

Investigate the relationship between height and arm span. Young statisticians measure the heights and arm spans of each class member and create a scatter plot using the data. They draw a line of best fit and use its slope to explain the...

Third graders investigate environmental stability through consumption and recycling. They look into how much of a recyclable good it takes to create one new product. Pupils compile a list of these quantities, then create posters that are...

With global temperatures on the rise faster than ever recorded, the effects of a heating planet could be devastating. Allow learners to discover just what the world is in store for if the warming continues through a series of videos, a...
